Examine these two statements carefully and decide if Assertion (A) and Reason (R) individually true and if so (R) is a correct explanation of (A) select your answer using the code below: Assertion (A): Magnesium imparts characteristic colour to the flame. Reason (R): Due to small size and high effective nuclear charge ionization enthalpy of magnesium is high. (1) Both A & R are true and R is a correct explanation of A. (2) Both A & R are true but R is not correct explanation of A. (3) A is true R is false. (4) A is false R is true.
Answer» (4) A is false R is true. Magnesium do not impart colour and its ionization enthalpy is high due to small size.
